Q: Should I buy the 550HP pump or the 1100HP pump?
A: If your car is street driven and the engine produces no more than 550 horsepower, the 550HP pump will work fine. If the car is primarily used for racing or if the engine produces more than 550 hp, the 1100HP pump is a better choice. The 1100HP not only produces more volume but the pressure can be adjusted higher so that a regulator can be used. A high pressure pump used with a regulator will provide steadier pressure than a low pressure pump.

Q: What if I buy a 550HP pump and later find that I need a 1100HP pump?
A: Any 550HP pump can be upgraded to 1100HP specifications for $100. Email us at robb@robbmcperformance.com for more info.

Q: Do I have to use a pressure regulator with the 1100HP pump?
A: Not necessarily. The output pressure is adjustable and if you reduce the pressure to about 7 psi, a regulator is usually not needed to prevent the carb from flooding. However, reducing the pump output pressure from 14 psi to 7 psi reduces the pump output volume by about 50%. So if the engine produces over about 550 hp, or if the car is used for racing, increasing the pump pressure and using a regulator is highly recommended.

Q: You don't list a pump for my engine. Can you make one?
A: In most cases, yes, as long as there is clearance on your engine for the large 4" diameter valve body. It also depends on the availability of pump arms and upper castings for your engine. The standard price for special order pumps is $200 for a 550HP version and $300 for a 1100HP version but the actual price may vary. Email or phone for more info.

Q: My car has a small factory "vapor return line" that was connected to the factory pump in addition to the inlet and outlet lines. Can I use this line with a RobbMc pump?
A: Yes. To use the vapor return line with a RobbMc pump, order part number 1010 along with the pump.

Note: Part Number 1010 is automatically included with Buick pump Part Number 1002.

Q: I am running a Q-Jet/Carter/Weber carb and the 7 psi produced by the RobbMc pump floods the carb. How can I lower the pressure?
A: If your car is equipped with a factory "vapor return line", you can purchase part number 1010 with your pump. This will reduce pump pressure by about 1 psi. If your car is not equipped with a return line (or you need even less pressure), you can add a non-return style pressure regulator between the pump and the carb.
